Patent CA-2108268-C (CA)
Title: Improved process for recovery of purified terephthalic acid
Inventor: STREICH DEBRA J
IPC: C07C51/47
Filed: 1992-04-09
Granted: 2003-02-04
Abstract: A process is disclosed for preparation of purified terephthalic acid containing 200 ppmw or less of p-toluic acid. A filter cake of purified terephthalic acid is prepared by filtering, under a differential pressure of about or greater than 0.5 psi over the system pressure and a temperature within the range of from about 100 °C  to about 205 °C, an aqueous slurry of purified tereph-thalic acid containing a solution of p-toluic acid. The aqueous solution of p-toluic acid remaining in the filter cake of purified ter-ephthalic acid is displaced from the filter cake by water under a pressure gradient over the system pressure at a temperature with-in the range of from about 100 °C to about 205 °C. Pressure flash evaporation of water remaining in the filter cake occurs upon release of the system pressure to lower pressure with consequent lower temperature. The crystalline terephthalic acid product con-taining 200 ppmw or less p-toluic acid can be dried under atmospheric pressure. Purified terephthalic acid is useful for the manu-facture of polyesters from which clothing and related goods are made.

Abstract: Regenerated cellulose food packaging film, including fibrous food casings have modified cling properties fox packaging dry and semi-dry type sausage products, and particularly specialty dry sausage recipes. The cellulosic food casings have a fibrous reinforcement impregnated with a coating composition containing an admixture of a viscose solution and a food grade cationic thermosetting polymeric adhering agent. The coating composition is applied in a single step by injecting into the viscose solution before being extruded into the fibrous web. This assures both even distribution of the polymeric adhering agent in the web, as well as maintenance of a constant level of polymer being applied during the coating process. The degree of cling/adherence of the casing to the meat mass is more uniform aver the entire circumference of the tubular casing.

Abstract: An acceleration detection device is provided which is capable of detecting accelerations in two or more directions. The base end of a beam is fixed to a support section on a board. A weight is provided in the front end of the beam which is formed so as to extend horizontally along the board surface with a gap with it and the surface of the board. The position of the center of gravity G of the weight is set at a position spaced perpendicularly apart from the center axis of the beam in order that the inertial moment acts when an acceleration along the length (in the X direction) of the beam is applied. The front end surface of the weight is formed into an upright surface of a movable electrode, and a fixed electrode is formed at a position facing the movable electrode with a gap therebetween. When an acceleration in the X or Y direction is applied, the beam is flexed upwardly or downwardly in proportion to the magnitude of the acceleration, causing the weight to be inclined upwardly or downwardly while being displaced upwardly or downwardly. Thus, the electrostatic capacity between the movable electrode and the fixed electrode increases or decreases. The magnitude of the acceleration can be detected on the basis of the amount of such change of the electrostatic capacity.
